Patented May 2,

Application filed April 12, 1921. Serial No. 460,728.

which the following is a specification.

This invention relates to device for interlocking two sliding window sashes 1n such a manner that the window cannot beopened beyond a certain and predetermined point.

. plied to window sashes.

One of the objects is to provide a lock that may be used to look a window fully closed and also lock awindow when not quite closed.

Another object is to provide a simple and durable lock, to be used in connection with window sashes. l 7

Another object is'to provide a lock or this type with a bar to slidingly engage with the coacting member between certain limited points and positions, having a locking member to prevent a closing when the device is in open position beyond such a locking member.

lowing description and appended claims as well as from the accompanying drawing, in ivhich- Fig.1 is a top plan view of the two locking members constituting the look when ap- Fig. 2 is a front elevation of the two members in Fig. 1.

Fig. 3 is an end elevation of the two members illustrated in Figs. 1 and 2, in interlocking position, portions of window sashes being indicated to show the relative position of the device to sashes.

The locking member 4; is normally applied to the inner and lower window sash, while the co-acting member or members must be on or near the lower edge of the outer'and upper window sash. i

In Fig. 1, the locking member a is turn ably mounted on the pivot 5 illustrated in unlocked position-in relation to the other parts of the device. The member dis normally for a horizontal swinging and turning movement. The base member 6 is pro vided with the pin 7 to form the-pivot-support for the swingably mounted armor bar 8. To look a window in the normal manner, a hook-like member 9 is provided on the bar 8 to be engaged by the inclined ,come-to the position ridge, bead, or edge 10 of the locking mem ber l the edgelO of the locking member 41 moving around thecenter 5. to eventually indicated in dotted lines at 11. I

The locking membere is normally attached or applied to the upper end of the inner sash of a window, while the base member 6 isnormally attached or applied near the lower end of the outer sash of the same window, the inner sash beingshiftable in an upwardly direction, while the outer sash beingshiftable in a downwardly direction, a when opening the window.

In Fig. 3, the two lockingmembers are shown in positions, illustrating that the in ner sash is moved to a position slightly higher than its normal closing position while the outer sash is moved or; me position slightly lower'than its normal closing position in relation to the inner sash, the inner sash being indicated at 12, and the outer sash being indicated atlQ, normally such sashes coming practically level. When the two sashes of the window are to be set away from their closing positions, the armB is moved to a practical vertical position, so that the locking member a can slide along the'baror a portion of the bar 8: Thelockingimember 4 is forthisp'urposle provided with an aperture 13,; and the arm 8 is provided with a bend. 14 and a downwardly extending portion 15, so that the locking member 4 can engage and slide over the portion 15 of the bar 5, limited in this movement by the bend 141. The arm 8 is made of a length equal to the movement desired between the two sashes of awindow, so that, by a sliding of the locking member 1 on the portion 15'of the bar Sup to the bond '14, the movement of the one windowIsash in relation to the other sasl'i is controlled in this manner. Making the bar 8 only six inches from its pivot connection at? up to the bend 14 means that'the. one sash can,

only be moved a short distance amounting lation'to the other sash.

When leaving windows open, it is normally desired to have'the one sash moved in relation to the other sash that aproper airing of a room may be accomplished without giving enoughspace for any oneto slip in, so that the room is thus still practically locked against thieves and other similar undesired visitors. The bar 8 can naturally be made of such a length to allow airing of a room without subjectingvthe. room to undesired intruders. w

v or looking a window fully, the bar8 is in practically horizontal positionrwith the hook-like member 9 proj ecti'ng' upwardly toengage over the locking member when this member 41s so turned to the position indi- 'cated at 11 in Fig. 1.

For opening a, window to some extent and still keep it under oontrolagainst' undesired intruders, the arm 8'is moved to" a practically vertical position with the hook-like member!) PTOJGCtlIlg si dewise asillustrated in Fi '3 and as indicated in dotted lines at 17 in Figs. 1 and2, so that, on turning the locking'member are closing position, the

aperture 13 comes to a position that t-he the portion 15, thereby locking the window sashesin open'position, a swingable lip 18 is provided. pivotally connected at 19 on the portion 15, within a recess 21in its normal positionso thatthe locking member 4' can slide over it up to the bend 14, when the lip is "swung out of engagingposition. When the lockingmember 4 is near the bend 14,

[that is near itsjuppermost position,,the lip pivot connection 19, so that the" looking can be swung upwardly to the position in- "dicated at 20 in Figs. 1 and 3. The lip member is of wedge-dikeshape, as illustrated, the pointed termination lying closer to the portion 1-5tha'n the attached end near its Jmember 4 can move downwardly: until it engages tightly over the. lip member'18 and theportion 15. The pin 19 is providednea one edge ofthe portion 15 and near'one edge of the lip member 18 to as illustrated.
